NUT-

LOCK.

SPECIFICATION forming part of Letters Patent No. 486,147, dated November 15, 1892.

Application filed February 18, 1892. Serial No. 422,007. (No model.)

To all whom t may concern:

a citizen of the United States, residing at Wytheville, in the county of Wythe and State of Virginia, have invented a new and useful Nut-Lock, of which the following is a specification.

My invention relates to an improvement in nut-locks, and has for its object the provision of a cheap and simple device for safely locking the nuts upon the bolts employed in railroad joints, moving parts of machinery, or other objects subjected to considerable vibrations.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claim.

Referring to the drawings, Figure l is a perspective view of a rail-joint embodying my improved nut-lock. Fig. 2 is a cross-section thereof through one of the locks. Fig. 3 is a detail of the locking-plate. Fig. 4 is a similar view of the locking-bar.

Like numerals of reference indicate like parts in all the figures of the drawings.

Although I have herein illustrated and described my nut-lock in connection withv an ordinary rail-joint, it will be obvious from the appended description thatthe same may be applied with equal advantage to the moving parts of machinery, and I therefore do not limit its use to that herein shown and described.

1 l designate two rail-sections the ends of which meet as usual and are clamped at opposite sides by the fish-bars 2, the outer ishbar in this instance being L-shaped, or substantially so, in cross-section, or, in other Words, having its lower edge terminating in a substantially-horizontal base which overlaps the bases of the rail-sections. The fishbars and webs of the rail-sections are perforated as is usual, and through the same pass the bolts 3, provided at their outer ends with the ordinary nuts 4.

5 designates my locking-bar, and the same bolt-opening 6 the locking-bar is provided with outwardly and inwardly projecting flanges 7, which flanges are preferably formed 'by means of openings formed in the lockingbar, the stock of the bar being punched outwardly, as shown.

The locking-plates 8 are of a width agreeing with the distance between the outer edges of the iianges at each side ofthe bolt-opening 6, and the vertical edges of the plates are rabbeted, as at 9, so as to take within the fianges, wherebythe plates may be inserted vertically drawal therefrom. The plates have their lower edges recessed, as at 10, in a rectangular manner, and hence are adapted to fit over and embrace the opposite iiat sides of the nuts. Above the recess of each plate the face of the plate is provided with one or more, and in this instance two, indentations or angular recesses or notches l1, into any one of which a chisel or other tool suitable for the purpose may have its end introduced, and by a tap or two with a hammer upon its opposite end is adapted to raise the plate from overthe nut and from between the flanges.

In assembling the parts, the bolts being in ish-bars, the locking-bar is introduced over the bolts and arranged against the outer lishbar. The nuts are now applied to the outer ends of the bolts and are run down upon the bolts to their positions against the outer surface of the locking-bar. After this has been accomplished it is simply necessary to introduce each locking-plate over its respective nut and between its respective pair of iianges with which the locking-bar is provided, and it is best to settle each locking-plate snugly in position by a slight tap of a hammer. Inasmuch as the lockingbar is held rigid by the parent that the locking-plates, being held between the flanges and embracing the nuts, will prevent any turning of the lat-ter, regardless of the jars or vibrations to which the railjoints are subjected by the passing thereover of the trains.

It will be obvious that when it is desired to introduce new bolts, when broken orimpaired, or new rails, the removal of the nuts will be a simple matter and may be accomplished in the manner heretofore described.

It will be seen that my lock is applicable to between the anges and are capable of Withposition and passing through the rails and clamping action of the nuts, it .will be ap.

the nuts and bolts now commonly employed in rail-joints and that I require no alteration whatever in any of the parts. It will be ob- Vious that when constructing new joints the outer fish-bar may be employed as the locking-bar, or, in other words, the flanges 7 may be punched or otherwise formed upon the fishbar, so that the additional bar herein shown need notbe employed, and hence in my claim hereinafter appearing, by the term lockingbar I mean the bar upon which the iianges are formed, whether it be the independent locking-bar herein shown and described or the fish-bar.

Having thus described my invention, what I claim is- The combination, with the rail-sections or their equivalents, the transverse bolts, and their nuts, of the locking-bar perforated t0 receive the bolts and located between the nuts and the rail-sections, said locking-bar being provided at opposite sides of the bolts with punched-out flanges, and the locking-plates mounted removably between each pair of iianges and having their lower edges provided with nut-receiving recesses, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
